USA Powder has blanketed the mountains in California, Utah and Colorado over the past few days. It is currently snowing in most resorts in these three states, and where it isn?t, it?s expected to this afternoon. The recent storm in the Sierras constitutes the heaviest snowfall the area has seen since 1916! The weather is very extreme across western states. Heavenly (205/270cm) and other Lake Tahoe resorts have a truly unreal quantity of fresh powder! Mammoth (180/240cm) is also wallowing in over a metre of deep fluffy powder. Skies are clearing over these resorts, but it will be a while before the groomers can catch up and there is a risk of EXTREMELY high winds gusting. At least 50% of the lifts are closed due to the sheer amount of new snow and strong winds. This storm fell as rain in SoCal, which has created wet and sticky conditions in the San Bernadinos. Driving conditions are perilous in many areas of CO, UT and CA: danger of flash floods, mudslides and avalanches abound. Snowstorms have also swept across the East Coast with dumps of up to 40cm in New York state, Pennsylvania Indiana and Illinois. All northeastern states have received at least 10cm of new snow, as has much of Quebec and Ontario.
